ELECTRICALLY-VHI-IZATED cooxme nsvros.

. Specification of Letters Patent.

Application filed June 8, 1912. Serial No. 702,472.

ToaZZ it may) concern:

- Be it known hat I, HENRY Pittsfield, in the county of Berkshire, S tate of Massachusetts, have invented certain new and useful Improvements in Electrically- Heated Cooking Devices, of which the fdlslowing is a specification.

Myinvention relates to electrically heated cooking devices','one of the objects of my in- I vention being to rovide a device of this character which will be suitable for carry ing out a plurality of cooking operations and at the same time will be light and com- 1 5 pact and, therefore,'easily handled.-

.My invention includes means for perform:

ing several cooking operations such as broiling, toasting,- boilingand frying. In order to secure compactness the same heat-- .20 ing unit is utilized for these operations and 3 Mg invention will be more clearly understoo v the arrangement. is such that the broiling may be one simultaneously with one' of the other operations. his is accomplished by making useof both sides of the heating unit, the-broilin chamber being located beilowthe-unit an -meansbeing provided for supporting articles above the same. Pref- I erably the cover of the 'boiling vowel or saucepan is of such shape that it may serve as another cooking utensil such as a frying pan and also as a cover for the heating unit.

Various other features and advantages of my invention will appearfrom the description which follows.

by reference to the accompanying drawings, in which I Figure 1 is a disas embled elevational view of myldevice; Fig". 2' isa horizontal section through the heatlng unit; Fig. 3 is a ver- .ticaL-transverse section-of that ortion of the 3 device comprising thev broil-chamber and heating unit Fig.1 4: is (a plan-view.'of the rid .of false-bottomof the broiling cham r; Fig. '5.v is an isometric. view of the frying pan weaver-ti the saucepan or heat ing unit.

- "As shown a s. land 3; the-.portion 10"of my apparatus havin a base portion 11 and a cover portion I I 2" is so ported through legs. 1f5 u on plate 14 w ich in turn is proviii'efiiw thspiral supports. 15. The plate 14 serves as a baflie to deflect the heat from the table upon which thefdevice I 555 be placed. The broiling chamber I which is formed by the arts 11 and12 is PRICE BALL, I a citizen of the United States, residin at provided with the false ottom or grid 16 which is preferably corrugated and. slotted so as to allow the juice flowing from the meat during the broiling operation to escape into the bottom of the chamber. The grid ,16 is reversible being supported b the v Patented Nov. 4, 1913.

sides 16" in the position shown in the rawing and having the bottom of the corruga:

tions in contact with the bottom of the chamber in the other position. This con-. struction allows an article .to be broiled at a higher or lower temperature as desired. The ends of the grid sides 16'. arecut away as at 16". This allows the. grid to'be readily removed. When it is .m' the positionshown In the draw ng, by pressing upon one end the other end may tie tiltedupwardly maklng it easily accessible to the operator. When the, grid is in the reverse position it may be readily removed by graspin the sides 16. The remov bility of the jgri .per-v .mits the broiler to be readily cleaned'.- It is also to be noted that when the grid is in the position shown in erable space is allowe for the collection of. 1 juices below thesame. The grid in either the drawing considsition serves -to prevent grease from being ignited as it constitutes a coolingscreen be tween the same and the heating..=tinit. The portion 12 which serves as a. cever'for the broiling chamber is provided with the han- 'dle 17 and is preferably hinged as at 18 to the lower or base portion 11. The top of this portion of the device is formed bygao two spaced grids or gratings 19, 20,,between which is supported the electrical resistance heating unit, .21. The said heating. unit comprises-theinsulating spacingbars 22 of porcelain or other refractory material through perforations :23 in which is threaded the electrical resistance wire 24 so as to form-a fiat unit-which is substantially coextensive with the top of the-chamber. The resistancewire is preferably of calorite described in "acertain Dempster Patent No. 901,428.. Perforations 25 m. 'be-formed in the side I ;'walls' of the cover 1 I the coils, which adds to the attractiveness of'the device when fin use. -'Terminals 26 so'as to. partly disclose areprovided for the resistance wire and for 3 a source of electric energy. A plate 26 is preferably mounted over the terminals to the reception of aplug to leads from boihng receptacle or saucepan 27 is pro vided with handle .28 and the bottom 29 tlfetdfis preferably coextensive with the upper grid and flat so that good thermal contactmay be secured between it and thesaid grid. The cover 30'for the boiling re-' ceptacle is of such shape as to be suitable for use as a frying pan and may be of aluminum so as to. secure the thickness of metal necessary for such a utensil without undue weight. It has a rim 31 and handle 32 and is adapted to fit closely over the top of the boiling receptacle or over the heating unit.

. By raising the cover 12 of the broiling chamber the meat to be broiled may be placed upon the false bottom or grid 16 and the. cover may be then swung to its former position. Energy maybe then supplled to the resistance heating unit and the heat heating unit.

will be deflected down upon the meat. The

broiling operation may be carried on at a higher or lower temperature depending on theposition of the grid. At the same time bread or other articles of food may be toasted by placing them upon the upper grid 20. Instead of utilizing the grid 20 for toasting, the saucepan 27 may be placed thereon and used for such operations as boiling or the cover 30 of the said receptacle may be inverted and utilized as a frying pan by placing'it upon said grid. It is apparent also that the member 30' may be utilized as a cover for the heating unit thus making the deviceinto a stove or griddle. The construction is such that a part of the heat furnished by the unit is deflected upwardly by the bottom of the 'broiling cham ber and a part is deflected downwardly by bodies placed upon the grid 20. This causes a very'efiicient operation as most of the heat is utilized for cooking. a

It is obvious that my device may be utilized for carrying out independently any one. of thecooking operations hereinbefore referred to. v 4
